OBJECTIVE: Previous studies suggest a possible association between using chiropractic care and lower influenza vaccination rates. We examined adult influenza vaccination rates for chiropractic patients to determine if they are different than those for users of other complementary and alternative medicine (CAM).

METHOD: We used the 2007 National Health Interview Survey to examine influenza vaccination rates among adult respondents who were considered high priority for the influenza vaccine (n=12,164). We separated respondents into clinically meaningful categories according to age and whether or not they had recently used chiropractic care, some other type of CAM, or neither. We used adjusted logistic regression to determine whether user status predicted influenza vaccination.

RESULTS: Only 33% of younger and 64% of older high priority Chiropractic Users were vaccinated in 2007; these rates approximated those of Non-CAM Users. However, younger Non-Chiropractic CAM Users were more likely than Non-CAM Users to have been vaccinated (p-value=0.05). In adjusted logistic regressions, we found statistically insignificant differences when comparing Chiropractic Users to Non-CAM Users for younger adults (OR=0.93(95% CI:0.76-1.13), or for older adults OR=0.90 (95% CI:0.64-1.20).

CONCLUSION: Chiropractic Users appear no less likely to be vaccinated for influenza; whereas, younger Non-chiropractic CAM Users are more likely than Non-CAM Users to be vaccinated.

I was introduced to Chiro.Org in early 1996, where my friend Joe Garolis helped me learn HTML, the "mark-up language" for websites. We have been fortunate that journals like JMPT have given us permission to reproduce some early important articles in Full-Text format. Maintaining the Org website has been, and remains, my favorite hobby.

    Interesting. I would have guessed higher rates of unvaccinated among the CAM users.

    This is a very interesting article on chiropractic patients who are less likely to be vaccinated. Its very interesting to note that cam users are more likely to be vaccinated.

    It would be nice to be able talk to patients about this topic more without controversy ensuing. I think most DC’s just don’t want to bring it up.
